Fluence distribution for the n-helix strategy. (a) Relative fluence as a function of the n-helix parameter for a circular beam of size 21/2L that exactly covers the square field of view (beam size = 1) and a beam size 1.5 times larger. (b) Relative fluence as a function of the beam size for a one-helix and an eight-helix strategy. (c) Mean relative fluence as a function of both beam size (y axis) and n-helix parameter (x axis). (d) Standard deviation of the relative fluence as a function of both beam size (y axis) and n-helix parameter (x axis). |
